Galileo Galilei – The Father of Modern Astronomy

This episode traces the extraordinary life of Galileo Galilei, the scientist who dared to challenge centuries of belief with the power of observation. Born in Pisa in 1564, Galileo abandoned medicine for mathematics and began experimenting with motion, discovering principles of inertia and acceleration. His construction of the telescope in 1609 opened the heavens: he observed mountains on the Moon, the phases of Venus, Jupiter’s four moons, and countless stars within the Milky Way. These discoveries supported the Copernican idea that the Earth orbits the Sun, directly contradicting the traditional geocentric model.

Galileo’s writings, accessible and witty, spread his ideas far beyond scholars, but also earned him enemies. In 1632, his Dialogue Concerning the Two Chief World Systems mocked defenders of the Earth-centered universe and brought him before the Inquisition. Forced to recant, he spent his final years under house arrest, blind but still writing. His work Two New Sciences laid the groundwork for modern physics, influencing Newton and generations that followed.

Though silenced in life, Galileo’s voice became a rallying cry for scientific freedom. He showed that truth rests in observation and evidence, not authority. His defiance against dogma lit the path of the scientific revolution, and his legacy endures in every telescope turned toward the stars. His quiet whisper, “And yet it moves,” remains one of history’s most powerful affirmations of truth.
